我很新的C雖然沒有節目,我是如此裸露..我主要感興趣的是得到一個C程序麻煩C程序執行另一個程序
的簡單目標,我只是想要得到一個C程序來做
c:\ windows \ system32 \ cmd.exe/k目錄 或 c:\ windows \ system32 \ cmd.exe /kc:\windows\system32\cmd.exe/k dir
我發現一個Windows的C編譯器..稱爲LCC-win32的
這裏是我使用的代碼,此刻只是愛民處的G推出的cmd.exe
#include <iostream>
#include <fstream>
using namespace std;
int main(){
ifstream inFile;
inFile.open("c:\windows\system32\cmd.exe");
if(!inFile){
cout<<"Cannot open file bish."<<endl;
system("pause");
return 1;
}
system("pause");
}
,但我得到了很多錯誤的 CPP:C:\ cprogs \ hw2.c:1找不到包含文件 CPP:C:\ cprogs \ HW2。 C:2找不到包含文件 和其他

我希望只是還發現,我可以修改網一些示例代碼,但我甚至不能得到任何這樣的代碼進行編譯。
--added ---
我發現一些示例代碼,我想通了,使\\「COS我一些編程經驗。
#include <stdlib.h>
int main()
{
system("c:\\windows\\system32\\cmd2.exe /v:on c:\\windows\\system32\\cmd2.exe /v:on");
return 0;
}
而且似乎工作
順便說一下,你正在編寫C++代碼,而不是C. –
很多小錯誤。如果你使用iostream和fstream,你需要一個C++編譯器。同下面的答案一樣,您正在從文件cmd.exe文件中讀取數據。那麼你會,如果你逃避你的反斜線字符。您需要在Windows中將路徑指定爲C:\\ WINDOWS \\ system32 \\ cmd.exe。嘗試一切,看看會發生什麼。 – arunkumar
至少我的(添加的)示例代碼起作用,並且是C! – barlop
